Suspension

Hey guys I'm new to this forum and I needed advice on lowering my car.

I wanted something that helped me straighten out my turns. I'm looking into something that has better performance than stock, but at the same time I don't want anything to extreme cause the roads in my City are terrible(Montreal).

I wanna spend less than 2k on hardware.

I was wondering if any of you dudes had suggestions. What types of shocks, springs I need....do I need sway bars.
